Abstract: A structure having fine ribs with a high dimensional precision is used as the rear panel of a plasma display or as a micro organism carrier for use in a chemical device. The present invention aims to provide a method for manufacturing such a structure at low cost. According to the invention, a composite sheet comprises a surface layer of silicone rubber and a base layer of a steel sheet. Grooves are formed in the surface layer, and filled with a paste material. The paste material is cured to form ribs. After a substrate is placed on the surface layer of the composite sheet, the composite sheet is pressed against the substrate from the base layer side, thereby compressing the ribs and adhering them to the substrate. Thereafter, the ribs and the substrate are removed from the composite sheet. As a result, a structure with fine ribs is obtained.

Abstract: A member is prepared by forming a magnetic surface layer on a magnetic base member having a different composition from the surface layer. A laser beam is radiated onto the member so as to fuse the member and the surface layer, thereby forming a fused portion having magnetic properties. A modified portion is formed in a portion of the fused portion corresponding to the surface layer such that this portion has different permeability from other portions of the surface layer.

Abstract: An ultrasonic fuel injection nozzle comprises a generator for generating ultrasonic vibrations, a vibrator secured to the ultrasonic vibration generator and a valve for supplying fuel to the vibrator. The vibrator is secured to the ultrasonic vibration generator at one end and is formed with a cavity in its other end portion for atomizing fuel therein. The vibrator has a fuel passage communicating with the interior of the cavity. A valve is provided for normally closing the passage and for opening the passage to discharge an amount of fuel depending upon the passage opening duration. A fuel atomizing portion serves to reduce the discharged fuel to minute particles through the effect of ultrasonic vibrations.

Abstract: A magnetic scale includes a magnetic base member and a thin film formed on a surface of the magnetic member by plating or flame spraying nickle, chromium, manganese, silicon, boron, carbon, or a combination thereof. A laser beam or an arc discharge is applied to the outer circumferential surface of the thin film to fuse the metal of thin film and the metal of the base member under heat for thereby forming nonmagnetic modified portions on the surface of the base member.

Abstract: A surface of a linear magnetic bar is subjected to such high density energy as a fine beam of laser rays, electrons, ions, plasma or an electric current to change permeability of portions subjected to the high density energy so as to form graduations spaced uniformly. A magnetic sensor is used to detect variation in the permeability, thus measuring movement, speed or acceleration of the scale relative to the magnetic sensor. The scale may be formed on a movable portion of a machine, for example a piston rod of a die casting machine or an injection molding machine.
